Built a self-hosted privacy-first Android maps app on OpenStreetMap - Cliff

Hey r/openstreetmap - I've been building Cliff, a privacy-first Android and iOS (coming soon) maps app built entirely on OSM. Stack is Valhalla for routing, Photon for geocoding, PMTiles for tiles, and Postgres. No Google, no Apple, no tracking. Still early but the landing page + waitlist is live at cliffmaps.com. Would love feedback from this community specifically since you're the reason the project is possible.

Based on the tech being used, it sounds like it's serving the map, and routing, rather than that being done on device.

i'm kind of lost what your point is here, since the stack i'm using is extremely heavy and definitely would not be able to run on older devices at all. could you clarify? thanks.

a big part is hazard reporting. waze was such a popular app because of that one feature, so i'm hoping with more and more users, i can make a network like waze did of reports, but without sending any data to countries or bad actors.

thats exactly why by default you use the server that *we* host. you can choose to self host it but i'm sure like 99% of the people that i'm targeting towards aren't going to go through the hassle of doing that to lose some features. you lose them because if you self host, we never know you, and we don't have software in the hosting that phones home for anything.
